For many years we have been offering a webmailer via webmail.uni-koeln.de, where you can use calendar functions in addition to pure mail functions. As the underlying external open source system Horde is no longer being actively developed, a change is unavoidable for security reasons. Access to webmail.uni-koeln.de will therefore be successively and irrevocably switched off from November 2025. The webmailer SOGo via sogo.uni-koeln.de is already available to you as an alternative system.
